There are two mid-century chairs in our house that we got for free. When you live in a college town like Austin, there's a lot of free furniture on the curb at the end of the school year. Most of it is puffy couches from the '80s, but we're incredibly happy with these two finds. Neither of them have any maker's marks or anything to identify them by, but we still love the look of both of them.
This green chair with no arms sits in the corner of our bedroom.
And this white chair sits next to our front door (and weighs about 45 pounds).
